Subject: [PATCH] ioctls: btrfs-control: fix header inclusion order
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch enables newer linux/btrfs.h in Kernel headers 3.11,
where NULL is not recognized as a define. This is done by
including  stdlib.h before linux/btrfs.h. It gets rid of the
following compiling error:

In file included from ioctls/btrfs-control.c:5:0:
/usr/include/linux/btrfs.h: In function ‘btrfs_err_str’:
/usr/include/linux/btrfs.h:486:11: error: ‘NULL’ undeclared (first use in
    return NULL;
           ^
